Specification of Letters Patent.

Application filed March 21, 1910. Serial No. 550,659.

To all whom it may concern:

Be it known that I, FERDINAND LUTZ, a citizen of the United States, and a resident of the city of New York, borough of Man-.

hattan, in the county and State of New York, have invented a new and Improved Siphon-Valve, of which the following is a full, clear, and exact description.

My invention relates to siphons, more particularly to siphon valves for water closets and the like, and has for an object to provide a valve for quickly creating a siphon for flushing purposes, which valve is durable and the action of which is simple and efiicient.

For the purpose mentioned, use is made of a short leg and a long leg, having a connection therebetween, a cylinder on the connection, and means in the cylinder and the connection for creating a siphon.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in both views, and in which Figure 1 is a sectional side view of a flushing tank having my device mounted thereon and showing the same in the act of creating a siphon, parts of the device being broken away to disclose the underlying structure, and Fig. 2 is a similar view but showing my device in its final position after creating a si hon.

eferring more particularly to the views, I provide a flush tank 1, having mounted therein a short leg 2, and a long leg 3 con nected to the tank at 4, and secured thereto by a suitable washer 5 and a lock nut 6. A connection 7 is shown intermediate the legs 2 and 3, and removabl secured to the lower end thereof is a cylinder 8 provided with a series of perforations 9.' A piston rod 10 is mounted on the short leg 2 and extends downwardly into the cylinder 8. At one end of the piston rod 10 a piston 11 is secured and adapted to slide in the cylinder 8. On the connection 7, in the upper part of the same, a valve seat 12 is provided, and. on the cylinder 8, in the upper part of the same, a similar valve seat 13 is provided, the said valve seats preferably being beveled to snugly receive a beveled valve 14, slidably mounted on the piston-rod 10, in the connec tion 7. A beveled stop lug 15 is rigidly mounted on the piston rod 10 at the upper end thereof, and is adapted to removably engage a beveled recess 16 of the short leg 2, as will be hereinafter more particularly described. In order to conveniently operate the piston rod 10, an eye 17 is formed in the upper end of the same, and mounted thereon, by means of a ring 18, is a lever 19, pivotally held on a bearing 20 secured to the tank 1, and the other end of the lever 19 is conveniently connected with a chain or cord 21.

The operation of my device is as follows: Supposing my device to be used in connection with closets, and the tank being full of water, as shown in Fig. 1, when it is desired to flush the closet the chain 21 is drawn downward, thereby raising the lever 19 and the piston rod 10. In viewvof the perforations 9 the cylinder 8 is filled with Water, so that when the piston rod moves upwardly the piston moves likewise and the water in the cylinder is forced upwardly through the connection 7. When the device is in its normal position, the valve 14 seats on the valve seat 13, but owing to the force of water pressing against the valve 14 when the piston moves upward, the valve 14 is forced to the upper part of the connection 7 and against the valve seat 12, thereby closing the entrance to the pipe or leg 2 and causing the water above the piston 11 to move outwardly through the pipe 3, connected with a flushing pipe in engagement with a closet. Now, when sufiicient water has passed out of the cylinder 8 and connection 7, and the pressure is decreased, the valve 14, owing to its weight, will drop to the valve seat 13 at the upper end. of the cylinder, and the suction caused by this movement will draw a stream of water from the tank 1 up through the leg 2 and, as the valve 14 has closed the entrance to\ the cylinder 8, the water will pass down through the leg 3, as shown by arrows in Fig. 2, and a siphonis created, which will continue until all the water is exhausted from the tank, thereby thoroughly flushing the closet. In order to 1 der, apiston: on the rod,- and' means sli'dably mounted on the rod and adapted to} operate limit the fall of the piston 11 in the cylinder in the' connection; V N
